I have Firefox Quantum web-browser version 57.0.2 (64-bit) in Windows 7.
The Sidebar
, unfortunately, has a maximum width of about 540 pixels.
I tried to increase this constraint by going to about:config
and searching for "sidebar". Then I changed the setting devtools.toolbox.sidebar.width;500 to a value of 600. Then I restarted Firefox. But it did not work.
So how can I increase the maximum width of the sidebar?
Confirmed in FF 66: No config settings work, but this method does. No way to improve it. – u2n – 2019-05-02T19:16:04.993
Did not work on FF 70.0.1. – wha7ever – 2019-11-12T15:46:34.330
Since version 69 and later, Firefox does not load userChrome.css by default. To make it effective again, open about:config in Firefox and set the preference
toolkit.legacyUserProfileCustomizations.stylesheets
to true – mini – 2019-11-29T08:42:18.560Does not seem to work on FF 71. – Marcin Orlowski – 2019-12-18T12:28:28.780
